Tumors of the skull base vary in stiffness; however,
stiffness cannot reliably be predicted with conventional
MRI sequences. Stiff tumors can result in a difficult
surgical resection with extended operative time and
increased risk to the patient. In addition, with the
increasing role of endoscopy, knowing tumor stiffness
prior to surgery could be critical to decide between an
open or endoscopic approach. The goal of this study was
to determine the potential of MR Elastography to
preoperatively assess the stiffness of skull base
meningiomas, pituitary adenomas, and vestibular
schwannomas.
